SEDlMENT-COLLECTOR FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 239,101, dated March 22, 1881.

-' Application filed January 1'7, 1881. (No model.)

of the boiler just above and in front of the less bridge-wall, the evaporation and commotion are greater at this point. The effect of this is to cause the heavy particles or scales to settle 'upon that part of the boiler to displace the lighter steam.

The object of my invention is to intercept the scales while circulating in the water, before they have settled upon the boilershell, and to collect them in a receptacle so that they can be readily removed.

In the accompanying drawings, in which similar reference-letters indicate identical parts throughout the various views, Figure 1 is a vertical transverse section taken through the grate-bars of a furnace and boiler, the latter fitted with my improvement. Fig. 2 is a central vertical longitudinal section of the same. Fig. 3 is an enlarged detail view of the hangers by which the scale'receptacle is suspended, and Fig. 4 is an enlarged perspective view (about one-half being broken away) of my improved receptacle and screen. In this View the screen is shown, as it is in Fig. 2, inclined toward the front of the boiler, and I have found that in this position it gives the bestresults. I

Referring to the parts, A represents a boiler of ordinary construction, having two flues, B B.

O is a rectangular sheet-metal vessel. It has pivoted within it a metal frame, D, within which: is stretched a screen, E, of wire-cloth or perforated metal. The screen-frameis held in either a vertical or inclined position by brackets F, which are secured to the ends of receptacle 0, and have notches f opposite each other to receive the edges of the frame D.

The frame is held between the, brackets by spring-pressure.

The device represented clearly in Fig. at is suspended from the lines (see Fig. 1) by hangers G. The hangers are made of wire looped loosely around the lines, so as to permit them to be moved along to the desired position. The lower ends of the hangers are hooked to pass each other through perforations or eyes in the corners of receptacle 0. The shanks of these hooked tongs are crossed, and are provided with slides g, which hold them together securely looked through the eyes of the receptacle, and which, whenmoved up to the point of crossing, permit the hooked ends to be sprung out of their eyes and the receptacle to be detached for removal with its contents. The upper portion of the screen-frame is curved upon each side to hug the lines and permit the reduced upper end to pass up about half-way between the fines B B. This brings the screen fairly within the backward current and in a position to intercept all the loose scale and sediment contained in the water, when it will drop into the receptacle. The wire-gauze I have found best is about No. 5. This is open enough not to interfere with the circulation, while tine enough to intercept all the scale and sediment, which usually settle on the shell of the boiler above the bridgewall, causing the boiler to burn or blister.

In Fig. 2 I have shown, in dotted line, a pipe leading downfrom the bottom of the receptacle. This is for use on steamboat-boilers in which the mud-drum is located just back of the bridge-wall. By this arrangement the scales may be discharged from the receptacle by opening the mud-valve.

The receptacle is suspended so that no portion of it shall touch the shell of the boiler. Thus the circulation is not interrupted, and there is no object upon the inside shell of the boiler around which scale will settle. It is evident that my suspended receptacle will produce good results even without the screen-deflector, but will not collect all the loose scale, and sediment, as it does with the screen.

I claim-- 1. The combination, substantially as specified, of boiler A and fines B B with closebottomed receptacle (3, said receptacle being suspended from the lines and above the shell of the boiler, all constructed and arranged as shown, and for thepurpose set forth.

2. In a boiler-scale collector, the combination of receptacle 0 with screen E, constructed and arranged as specified.

3. In a boiler-scale collector, the combination, with receptacle 0, of the tongs-hangers Gr, and slide g, arranged as specified.
